Background technology
Home electric appliance plug/the socket of Ying Yonging in the market, mainly be divided into two big classes, one class is not to be with the ordinary plug/socket of defencive function, this type of plug has been the connection effect, circuit to the rear end is not effectively protected, when causing the fault of fire, can not in time make protection, the people's lives and property is threatened safely; Another kind of is the protection plug of band defencive function; this type of plug has temperature, overload, overvoltage, residual current protecting mostly; and it is empty short, empty disconnected and fault electric arc that produce does not have effective detection method to the circuit that occurs in the back-end circuit; and the fire that fault electric arc causes, serious threat is to the people's lives and property safety.
The utility model content
The utility model provides and can play timely and effective protection rear end household electrical appliance in appliance plug/socket field, can detection failure electric arc, and have the plug that temperature detection is sent warning.
In order to realize the foregoing invention purpose, the utility model has adopted following technological means: fault electric arc formula temperature inspection plug, comprise the plug main circuit, and described plug main circuit is connected with fault electric arc detection module and switching power supply; Described switching power supply is the CPU power supply; Described CPU also is connected with temperature detecting unit, trip unit and acousto-optic warning unit; Described temperature detecting unit is installed on pin or the contact.
As preferred version: described fault electric arc detection module comprises high-frequency signal sampling unit, signal processing unit, power supply collecting unit at zero point and fault electric arc analytic unit.
As preferred version: described trip unit comprises high-voltage bidirectional optocoupler, controllable silicon, tripping coil and filter circuit.
As preferred version: described temperature detecting unit is thermistor.
As preferred version: CPU also is connected with acousto-optic warning unit.
The beneficial effects of the utility model are: because fault electric arc formula temperature inspection plug is provided with fault electric arc analytic unit and trip unit, can detect the electric arc that exists in the circuit of rear end, and can distinguish the type of electric arc, be general electric arc, the fault electric arc of good arc or energy initiation fire, as detect fault electric arc, CPU can be given an order, a mouthful unit action is taken off in control, disconnect back-end circuit, the wiring board rear end because the empty short or empty disconnected electrical fire that causes plays effective detection and disconnects buffer action, is made because the electrical fire that fault electric arc causes is prevented trouble before it happens.Because fault electric arc formula temperature inspection plug also is provided with temperature detecting unit and acousto-optic warning unit, can detected temperatures whether meet standard, and when exceeding standard, trigger trip unit, disconnect back-end circuit.Acousto-optic warning unit can give the alarm when back-end circuit disconnects, and comes into the picture, and has further increased fail safe.
